' BUFFER on nurouonmns.

, Patented Nov.

To all whom' mag concern:

Be it known that we, JAMES T RNER and PEARL P.'CRAB1L citizens of theUnited- States, residing at Springfield,in the county of Clark andStatejof Ohio, have invented certain new and useful Improvements 'inButlers for Automobiles, of which the following is aspecification.

This invention relates to'improvements in bufiers especially adapted forautomobiles.

An object of the invention is to provide a bu'fler which may be quicklyand readilyattached to the VehiCleWithO'utthe necessity ofalterationsfas the drilling of holes in the frame of the machine or'theremoval of any of the parts thereof.

A further object of the invention is to" provide means whereby thebu-fierrnay be adjusted-so as to maintain the buffer springs v and barin a straight .horizontal. position with respect to themachi'ne to whichit is the vehicle.

Th invention consists in the construction ii'i the. claims."

I

b is the buffer bar ofour improved device, which extends transverselyacross-the front of the vehicle and is.'constructed'inthe usual andordinary manner. This bar extends through and is secured to collarsb,each of said collars beingprovided with a set-screw elliptic springspivotally connected at the b for the purpose. Each-of these collars hasa rearwardly extending sleeve 6 which is slidingly mounted upon a rodbflwhich pro jects iorwardly fr'om'the' head or frame;

which clamps the device to the vehicle this head or frame consistingessentially of two parts 0 and 0., pivotally connected toether I in themannerhereinafter more f y de scribed. A coiled spring 6 laced about thesleeve 12 and the boss I) on the-forward part of the head orwardly; a

portion a, serves jto' normally. proj ect the 00 art and hencethe-buffer bar pin 6 extending throug'hihe .rod 32 with its endsprojecting laterally the sleeves'iunder the stress of the springs.

.As before stated, the respective portions 0 and .c of the head or frameare pivotally" connected together, the pivot being in the nature of ascrew bolt 0 (F i'g, 7) which exthe part c and is screwed intohe'respective parts of the head curved s otted opening 0 in the part aand is fscrewedintothe part 0' (Fig; 6 a washer e jfbein interposed'jbetween .the' ead of the bolt an the side of the part'c, as shown.

- Theres'pectiveparts of the head where'they channel frame a, and isadapted to be fitted thereto." Depending from the rear portion of theart a is'a stationar clam in meme P y P g her 0, which may be formedintegrally with said part, c. The depending portion 0 has securedthereto at its lower end a laterally projecting rod 0 which terminatesin a re- "duced screwthreaded portion 0 said rod 0 being secured to thedepending portion 0 by the nut c screwed onto a reduced portion of therod 0 which reduced portion projects through a perforation in the part0. The head part 0 has a screw-threaded opening located on the oppositeside of the depending portion 0 adapted to receive a clamping screw, the'head of which is represented by 0 0 is a movable clamping member whichcooperates with the stationary 'clampin member 0? and is perforated atits top an bottom so as to receive the clamping screw,

and 0 may be provided with a' series of perforations as indicated at 0so as to accommodate the device to different sizes-of channel frames.The rod 0 is also provided with a set screw 0 which is tightened againstthe bottom of the'channel frame, a, to. assist in holding the device inposition. Each of the clamping members are recessed as indicated at 0 inorder to accommodate in some cases both heads in the channel frame.

After the device has been firmly clamped to the channel, byloosening theclamping bolt 0, the portion 0 of the head may be ad justed so as tocause the rod 6 thereon-to project in a straight horizontal position andhence maintain the buffer springs and other parts in av horizontalposition so that any thrust upon any of the parts may be a direct one.

It will be seen by this construction that the device may be attached toa vehicle with out the necessity of altering or removing any of theparts of the vehicle and that a large part of the shock of "a collisionwill be brought directly upon the ends of the channelframe, a.

Having thus described our invention, we claim:

1. In a bufi er for vehicles, a buifer bar,

and means on each side of the vehicle for connecting said bar thereto,said means comprising a two-part head adapted to be secured to saidvehicle, the respective parts of said head being pivoted together,together with devices for clamping the re spect-ive parts of said headtogether, substantially as specified.-
